DUST-SEPARATOR.

Specification of Letters Patent.

Patented Jan. 4., 1910.

Application filed August 27, 1909. Serial No. 514,865.

To all whom it may concern:

lie it known that. we, HERBERT D. Vans and NoAn Bax rnn, citizens of theUnited States, residing at Anderson, in the county of Madison and Stateof Indiana, have invented certain new and useful Improvements inDust-Separators; and we do declare the following to be a full, clear,and exact description of the invention, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to apparatus comprising parts of vacuum-cleaningapparatus of the class that is employed for removing dust from carpetson floors, or for cleaning various articles; the invention havingreference particularly to apparatus whereby the dust may be separatedfrom the air that is utilized for removing the dust from the articles.

The object of the invention is to provide an improved dustseparator ofthe above mentioned character that will be adapted to be constructedcheaply and be durable and economical in use; a further object being toprovide a dust-separator that will thoroughly separate the dust. fromthe air and be adapted to be readily cleansed as occasion may require; astill further object being to provide a dust-separator that will operateeffectively without the use of water and which will be free fromdelicate arts that would be liable to become deranged.

\Vith the above mentioned and minor ob' jects in view the inventionconsists in the novel parts, and combinations and arrange ments ofparts, as hereinafter particularly described and then defined in theaccompanying claims.

Referring to the drawings, Fi ure 1 is a vertical central sectional wow0 the dust.- separator as preferably constructed; Fig. 2, a horizontalsectional view approximately on the line AA in Fig. 1; Fig. 3, a fragmentary front elevation partially broken away; Fig. 4, a fragmentaryperspective View of the suction-pipe of the apparatus; Fig. 5, ahorizontal section on the line BB in Fig. 1 looking upward; Fig. 6, afragmentary section on line G-C in Fig. 1; Fig. 7, a perspective view ofa art of the inlet pipe of the apparatus; an Fi 8, a fra mentarsectional detail of the c caning-hie door 0 the receptacle.

Similar reference characters in the diifen ent figures of the drawingsindicate corresponding elements of features of construction referred toherein.

As preferably constructed the invention comprises an upright cylindricalshell, numeral 1, in the lower portion of which is secured a bottom 2, aportion of the shell extending below the bottom to serve as a basewhich, however, may be otherwise provided if preferred, the lower end ofthe base portion being provided with a base-ring 8. The upper end of theshell of the receptacle is provided with a joint-seat t on which is apacking-ring 5, a lid 6 having a flange 6 being seated removably on thepacking-ring, the flange extending into the shell. The lid thereforewill be held tightly on its seat when a partial vacuum is formed in there ceptacle. A suction-pipe 7 extends through the bottom 2 and upward inthe receptacle centrally and terminates with an open end near the lid 6,the pipe being secured tightly to the bottom and having an elbow 8connected thereto below the bottom, a horizontal pipe 9 being connectedto the elbow and extending out through the base part of the receptacleshell, to e connected with any suitable apparatus for producing vacuumor partial vacuum. The pipe 7 has a collar 10 thereon at a suitabledistance above the bottom of the receptacle. A guide sleeve 11 has aconical-shaped deflector 12 attached to the bottom thereof and is placedremovably on the pipe 7, and normally rests on the collar 10, thedeflector bein annular and extending nearly to the shefi 1 or body ofthe receptacle. A tubular screen 13 having perforations 14 therein hasone end secured on the to of the deflector 12 and extends upward eyondthe plane of the upper end'of the pipe 7 the upper end of the screenbeing provided with a cap or closure 15 that is seated removablythereon. A strainer 16 composed of suitable fabric is sleeveshaped andis placed over the screen 13 and has a top 16 that rests on the cap 15,the lower end of the strainer being secured to the screen 13 at thelower end thereof by a band 17 provided with a buckle 18, so that thestrainer may be readily removed from the screen in order to clean it orreplace it by a new strainer.

An inlet ipe 19 extends through the base ortion of t e shell 1 below thebottom 2 and as an elbow 20 connected to its inner end,

a vertical pipe 21 extending through the bottom 2' and being connectedto the elbow, the pipe 21 having a curved terminal portion 22 that opensunder the deflector 12, the terminal end bein r curved slightly towardthe horizontal an also so as to discharge toward the axis of thereceptacle to produce whirling currents under the deflector in order todistribute the dust over the bottom 2 as much as may be. The pipe 19 maybe connected to any suitable suction-pipe system or with a suction toolor implement for removin dust from carpets or the like.

The shell 1 of the receptacle preferably has a doorway 23 therein nearthe bottom 2 and provided with a door-frame 24- suitably flanged, a door25 being fitted to the doorframe and provided with a joint-packing 26,the door being removable and normally held in its place by clamps 27 andsetscrews 28; or the door may be otherwise mounted on the door-frame ifdesired.

In practical use partial vacuum will be maintained in the suction-pipe Tand coir sequently throughout the receptacle and within the screen by asuitable exhauster, so that suction will be induced in the pipe 21through which air and dust will enter the re ceptacle and be deflecteddownward by the deflector 12, the air and lighter particles of asspassing around the deflector and upward to beseparated by the strainerand tl'isuction-pipe 7 and out to the exhaustcr, while the dust willgravitate. toward the bot tom of the receptacle.

When the apparatus is not in use the lid 6 may be removed and then thestrainer and deflector may be removed from the suctionpipe and taken outof the receptacle to be cleansed, and after removing the strainer fromthe screen the cap 15 may be removed in order to cleanse the interior ofthe screen if required. The dust, of course, may be removed through thedoorway 23, or in small portable sizes of apparatus the receptacle maybe inverted so as to remove the dust from its open top.

Havin thus described the invention what is claim as new, is

' 1. A dust-separator including an upright closed rece tacle, asuction-pipe extending vertically in the recetacle and provided with acollar on the collar, the guide-sleeve extending about the suction-pipea screen attggl red to the top gt' thg deflector and having a capthGIGtlll, t t jl.l'ilii1li1 WQXlQllLliJlg about the ififlm aud aniulct-pipe extending into the receptacle and terminating under the deflector.

2. A dustseparator including an upright. receptacle, a lid seatedremovably on the receptacle, a suction-pipe extending vertically in thereceptacle from the exterior thereof and provided with a collar,anannular conicallyshQBQLLMdQIiect r PIOVldtKl with a giiidfileeve andseated reniovably on the collar, the guide-sleeve extending about thesuction'pipe a screen attached to the top of the deflector and extendingabout the suctionpipe, a cap seated removably on the top of the screen,str r i neron these-teen and having a top seatd on the cap, a. bandsecuring the strainer to the screen, and an inlet-pipe extending intothe receptacle and terminating under the deflector.

3. A dust-separator including an upright receptacle having a bottom andhaving also a doorway in the side thereof near the bottom, a doornormally closing the doorway, a paclcing-ring on the top of the wall ofthe re ceptacle, a lid seated on the packing-ring, a suctioirpipeextending through the boitom and vertically upward into the receptacleand nearly to the lid and having a collar thereon, an annula gnicalbgshaped m; tlector extending about the s uctionpipe and on thecollar, a guide-sleeve attached to the deflector and extending upwardabout the suctionpipe, a tubular screen attached to the top of thedem'xfending about the suctiolrpipc and upward above the plane of thetop thereof, a cap on the top of the screen, a sleeve;sl' a,p edstrainer extending about thescieln and haviiig't'op that exr 1e cap, aband securing the lower end of the strainer to the lower end of thescreen, and an inlet-pipe extending through the bottom of the receptacleand having a curved terminal end extending under the defiector.

In testimony whereof, we aiiix our signa tures in presence of twowitnesses.
